Which Windows Server version should you choose?
Choose Server 2025 if…
You need the latest version with extended support until 2035, Azure Arc integration, hotpatching (updates without reboot), enhanced security (Credential Guard, VBS) and maximum compatibility with new hardware.
Choose Server 2022 if…
Your infrastructure already runs on 2022, you don't need to migrate yet, you want proven stability and support until 2031. Same price as 2025 at Revolution Soft (€249).
Choose Server 2019 if…
You need legacy application compatibility, have existing servers running 2019 and want to expand, or need the Essentials edition (no CALs required, up to 25 users). Extended support until 2029.
Choose Server 2016 or 2012 R2 if…
Your specific software or hardware is only compatible with these versions, or you need an affordable licence for a test/development environment. Note that 2012 R2 no longer has standard Microsoft support.
What are CALs and when do you need them?
A CAL (Client Access License) authorises a user or device to connect to a Windows Server Standard or Datacenter server. It's not software — it's a legal access right. The Essentials edition doesn't require CALs (it already includes up to 25 users).
There are two types: User CAL (one per user, regardless of how many devices they use) and Device CAL (one per device, regardless of how many users share it). User CALs tend to be more cost-effective when each person uses multiple devices (laptop, phone, tablet). Device CALs are better when a computer is shared across shifts (factories, hospitals, classrooms).
RDS CALs (Remote Desktop Services) are required if users connect via Remote Desktop. They're separate from regular CALs — you need both. At Revolution Soft we sell 50-pack RDS CALs from €165.

Frequently asked questions about Windows Server licences
How much does a Windows Server licence cost?
At Revolution Soft, Windows Server Standard (24 cores) costs €249 and Datacenter (24 cores) costs €299 (VAT included), for versions 2016, 2019, 2022 and 2025. Microsoft charges over €1,100 (excl. VAT) for a Standard 16-core licence through their official channel.
Are these licences legal?
Yes. These are surplus software licences sold under CJEU Ruling C-128/11, which recognises the right to resell software within the European Union. They are original, perpetual licences valid for Microsoft audits. Revolution Soft is a Spanish company registered as an S.L.
Do I need CALs with Windows Server?
Yes, for Standard and Datacenter editions you need a CAL per user or device connecting to the server. The only exception is Essentials, which includes access for up to 25 users without additional CALs. If you use Remote Desktop (RDP), you also need separate RDS CALs.
What's the difference between Standard and Datacenter?
The main difference is virtualisation: Standard allows up to 2 Windows Server VMs (with Hyper-V), while Datacenter allows unlimited VMs. Datacenter also includes advanced features like Shielded VMs, Storage Spaces Direct and Software-Defined Networking. If you only need 1-2 VMs, Standard is sufficient and more affordable.
How many cores does each licence cover?
Our Windows Server licences cover up to 24 physical cores. Microsoft's minimum requirement is 16 cores per server. If your server has more than 24 cores, you'll need additional licences or Core Add-On packs to cover the extra cores.
Do you issue invoices with VAT?
Yes. Revolution Soft is a Spanish company (S.L.) and issues invoices with 21% VAT itemised on all purchases. The invoice is valid for tax deduction by businesses, freelancers and public administrations in Spain and the EU.
Do you offer volume discounts?
Yes. Our reseller programme offers 30% off Windows Server, SQL Server and RDS CALs, and 20% off the rest of the catalogue. For one-off high-volume purchases, contact our sales team for a custom quote.
